160 Gbit/s ATM switching system for public network

The ATM (asynchronous transfer mode) network is regarded as effective for a multimedia telecommunication environment that enables high-speed and broadband communication. This paper reports the development of the FETEX-150 ESP (Enhanced Switching Platform) which has been designed as an ATM switch in a public broadband network. To track the latest ATM standards and trends, a simple, scaleable, and open architecture was set forth for the FETEX-150 ESP design target at the beginning of the system design. This paper describes design concept and system architecture of the FETEX-150 ESP system from hardware and software design viewpoint. Also, this paper describes traffic management, system features and operation and maintenance features in the FETEX-150 ESP.
